NisLs G. oLsoN, or' BUFFALO', 'New Yong-AND 'Amm fr. Baanows, or BRUNSWICK,

To all whom it may' concern.'

Be it known that we, Nans G. OLSON, a subject o f the King of Sweden, residing at Buffalo, 1n the county of Erie and State' of 5. New York, and Arian T. BAiuiows, a citizen of t-he 'United States, -residin wick, in the county of Cum rlandand' State of Maine, have jointly invented cer-' at Brunstain new and useful Improvements 1n Wave- Motors, of which the following is a speciication.

Our invention' relates to wave motorsv adapted to utilize the power'ofgwaves forconversion in any suitable mannerinto const-aiit power for running machinery.. and has for its primaryobject the provision. of a simple and inexpensive apparatuscapable of use in connection with vany natural body of water, the rise and fall of the-waves being utilized to im art movement lin a vertical or a substantially vertical plane to a float anchored to allow such movement.'

It also has for its object'the provision of movement-converting mechanism of simplitied construction whereby the vertical or substantially vertical movements of a float actuated by the waves are converted into rotary movement to be used for 'storing water or for driving machinery directly or through the medium -of the stored water, as may be desired. i*

To these ends our invention consists in the novel features of construction and in the arrangement and combination of parts to be hereinafter described and more particularly pointed out in theV subjoined claims.

Figure 1 is a sectional elevation of a wave motor embodying the principles of our 1nvention in what wevnow consider lts preferred form. F ig. 2 is a transverse section taken on line 22, Fig. 1*, on a reduced scale, looking in the direction of the arrow crossing said line.4 Fig. 3 is a horizontal section on a reduced scale taken on line 3 3, Fig. 1. Fig. 4 is a sectional elevation of a wave motor embed ing the principle involved in a modified orm. Fig. 5 is a transverse section taken on line 5 5, Fig. 4. Referring aow to the drawings in detail, similar munerals of reference refer to similar parts in the :wvl-ral figures.v

The reference numeral 6 designates a i'rauie which comprises two uprights 7' llaving their lower mls embedded in 01' fastened in any suitable manner to sub-struc wave-ironica.

tures 8 formed ofconcrete orA the like.

r1 hese uprights aieconnected. at their up-" per ends by thecross-beain 9, to the underside of. which'is secured a bracket 10 in which 1s rotatably held a cable sheave 11.

Arranged centrally between the. -sub-struc- 'the bed of the body of water so that the superstructure secured thereto, which is preferably constructed of iron, will withstand the force of the waves and `elements of the weather. Manifestly any' other structure* -s'ui table"for the -purposemay be utilized and in'someiplac'es the natural formation of'the cliff orshdre may be utilized to support the parts intended to be supported by the framework described.

15 designates a floatwhich is circular in formation and comparatively flat to provide an extended surface areaand to assure, as near as may be, avertical movement of the same. This float is positioned centrally between the uprights 7 and from its periphery has exten ing'outwardly a series of radiating anchor cables 16.` These cables .may extend a considerable distance from the -float and be anchored, as at 17, Fig. 2. By extending these cables a considerable distance the float is allowed a vertical or substantially vertical motion while being permanently held in place between the uprights 7.

Secured centrally to the float. at the top is one end of a power cable 18 which passes upwardly therefrom and around the sheave 11, thence shoreward where it passes around a 'drum 19 secured to a. shaft 20 which is journaled in a frame 21 of any suitable construction, said frame being fastened to a suitable structure 22 which may extend out over the body of the water, if desired. Said power cable is wound around the drum several times and thence directed outward and downward toward the bedof the body of the water so as to pass around the sheave 14 and finally inward for connection with the ends of a series of equalizing cables 23 fastened equal distancesfrom the 'center of the float at the underside thereof and converging therefrom toward a common point, said series of cables being' fastened to the float as described and having common.connection ing therefrom to said drum, It is apparent.

that by extending the anchor cables outward a suitable distance in radiating lines,.sutii cient slackness is provided to allow the rise and fall ofthe float with the waves, but such slackness will not admit of the float moving materially out of the plane .in which it is ositioned. When the float is caused to rise Ey the waves the stretch of the power cable 18 extending from the top 'of the ioat to the drum 19 is slackened,while4the. stretch of said cable extending from the drum to the series of converging equalizing cables 23 'is drawn upon Iin a direction away from said drum, thus allowing the float to rise 'and the motion of the cable to beimpartedto the drum so as to rotate the latter in one direction.v When the float 4lowers with the passing of the waves the stretch of the power cable 18 extending from the top of the float to the drum is drawn upon while the stretch of the cable extendin from the drum to the converging equilizing cables secured to the underside of the float is slackened, thus permitting the float to lower and causing the drum to rotate in the opposite direction. It is clear, therefore, that the shaft to which the drum'is secured is given alternatingly reversible rotary movement which may be utilized for actuating any alternating pumpfor pumpinv water to anyv desired height, or by means ofsuitable mechanism interposed between the drum and the part actuatedby the shaft, said alternatingly reversible rotary movement may be converted into direct rotary motion;

In the modiiication shown in Figs. 4 and 5 the framework is dispensed with, also the connection between the upper side of the .float and the drum. In this modifications.

connection to said equalizing cables down-- ward around a sheave 27 secured in a bracket '28 fastened to an anchor block 29 rising from the bed of the body of water. From the sheave 27 said cable is directed upwardly and shoreward and is wound upon a drum 3U, the end of the cable extending downward from the drum and having secured to its extremity a weight 31. The drum 30 is fastened to a shaft 82-in any approved manner, which shaft is journaled in i 'means for causing4 Said oat to move in a substantially vertical plane, a vdrum rotatably mounted, converging equalizing cables secured to said float, and a power cable connected 'to said equalizing cables and passing around said drum.

2. A wave motor comprising a float, diverging anchor cables connected to said float, a rotatable element, a cable sheave located above the center of said -ioat, a cable extending directly upward from the center of said float and .passing around said sheave and thence to said rotatable element, and means connected to the underside of said float to cause itto be drawn downward in a vertical or substantially vertical plane.

3. A wave motorA comprising a float, diverging anchor cables connected to said float, a drum rotatabl mounted, cable lsheaves located above an beneath said float 1n a plane passin through the center of the float, a power ca le wound upon said drum and extending therefrom around said sheaves and thence toward said float for connection thereto.

4. A wave motor comprising a ioat, diverging anchor cables having one of their endsconnected to 4the periphery of said float, a drum rotatably mounted, and a power cable wound between its ends upon said drum and having its ends connected to. the top and bottom, respectively, of said fioat to cause it to movein a vertical or substantially vertical plane.

5. A wave motor comprising a float, diverging anchor cables connected to said float, a rotatable element, converging equalizing cables secured to the underside of said float, and a power cable connected to said rotatable element and passing therefrom for 4connection to the top of said float at itsl rights and having a cable sheave secured thereto, of a oat positioned centrally between said upright's, equalizing cables secured to the underside of said float and directed inwardly and downward from their points of connection to said loat toward a common point, a rotatable druma distance from said float, and a power cable wound around said drum and passing therefrom in two stretches, thence around said sheaves and inall toward4 the center of said float, one end eing connected centrally to the upper side of said float and the other end having connection with said equalizing cables.

In testimony whereof, We have aixed our signatures in the presence of two subscribing witnesses.
